Accessibility: Does Siteimprove check for captioning on videos and other multimedia?

Summary

Yes. Siteimprove checks for captioning on videos and multimedia using WCAG criteria, but these checks are semi-automated and require manual review to confirm accuracy.

Answer

Yes, Siteimprove does check for captioning on videos and other multimedia. We check against the following success criteria:

• 1.2.1 - Video/audio needs alterative
• 1.2.2 - Multimedia content needs captions
• 1.2.3 - Multimedia content needs alternative

The checks we provide are semi-automated, which means that validating the issue requires a guided review. 

You can read more about guided reviews in the article "Accessibility: Reviewing Potential Issues".

Note: Information on our Accessibility product can be found in Learn more about Accessibility.
